RAPIDS cuGraph库是一组图形分析,用于处理GPU数据帧中的数据 - 请参阅cuDF。 cuGraph旨在提供类似NetworkX的API,这对数据科学家来说很熟悉,因此他们现在可以更轻松地构建GPU加速的工作流程。
示例代码:
import cugraph # assuming that data has been loaded into a cuDF (using read_csv) Dataframe # create a Graph using the source (src) and destination (dst) vertex pairs the GDF G = cugraph.Graph() G.add_edge_list(gdf["src"], gdf["dst"]) # Call cugraph.pagerank to get the pagerank scores gdf_page = cugraph.pagerank(G) for i in range(len(gdf_page)): print("vertex " + str(gdf_page['vertex'][i]) + " PageRank is " + str(gdf_page['pagerank'][i]))
